Provide bin/storage quickstart to automate generation of quickstart.sql
Ref T1191. Currently, the quickstart.sql gets generated in a pretty manual fashion. This is a pain, and will become more of a pain in the world of utf8mb4.
Provide a workflow which does upgrade + adjust + dump + destroy, then massages the output to produce a workable quickstart.sql.
Test Plan: Inspected output; I'll test this more throughly before actually generating a new quickstart, but that's some ways away.
